One-Page Modern Cabinet Calculator UI

I already have a high-resolution photo mock-up that shows exactly how the cabinet-door calculator should look. Your job is to turn that image into a single, production-ready screen with a modern-minimalist feel.

Core elements to build
• A small gallery area for door style photos
• Clearly labelled input fields for dimensions, finish options and quantity
• Space for supporting information such as price notes or warnings

This is UI only—no calculation logic or database hooks are required. The layout needs to be fluid across desktop, tablet and mobile breakpoints, and coded with clean, well-commented HTML, CSS and light JavaScript for any basic interactions (e.g., expanding info sections). Keep the colour palette neutral, typography simple and whitespace generous to match the minimalist direction.

Deliverables
• Responsive page files ready to drop into our existing project
• Assets and source files (CSS, JS, images) neatly organised
• Quick hand-off notes so my developer can wire it to the calculator engine later

If an interactive slider or chart ever becomes necessary, leave a clearly marked placeholder, but for now focus on the gallery, input fields and accompanying text. Please let me know your estimated turnaround and any clarifying questions you might have.
